Polyester threads are a popular choice for many sewing applications. Its versatility is unmatched and can be made to look and feel like different fiber types, such as cotton and silk. We have a wide selection of polyester threads from a fine monofilament thread for invisible stitching to thick, decorative corespun threads for bold topstitching. Our polyester threads are available in solid and variegated colors, depending on the thread line.

It is an extremely fine thread that can be sewn with a very small needle, rendering the thread virtually invisible.

100 wt. (.004" in diameter). MonoPoly is a reduced-sheen monofilament polyester thread and is the best choice when it comes to invisible threads. Unlike other monofilament threads made from nylon, MonoPoly is 100% polyester. Commonly referred to as an invisible thread due to its fineness and reduced-sheen, MonoPoly is great for the bobbin or top. Available in two colors, smoke (for dark fabrics) and clear (for light fabrics). MonoPoly is ideal for invisible applique and quilting when the stitching is not meant to be seen. MonoPoly is recommended over nylon monofilament threads because MonoPoly will not become brittle over time (nylon monofilament thread tends to go brittle), MonoPoly will not discolor (nylon monofilament thread tends to yellow over time), and MonoPoly is dryer and iron safe on medium heat.
